High Temperature Chamber Furnaces, Laboratory and Industrial Furnaces

Established in 1938, Carbolite has over 60 years experience in the design & manufacture of electric laboratory & industrial furnaces, laboratory & industrial ovens & incubators.

During this time, Carbolite has established an enviable reputation for its ability to design and manufacture quality products for standard & special applications for laboratory, pilot scale & industrial applications.

Laboratory Furnaces

The extensive portfolio offered by Carbolite includes both laboratory chamber furnaces & laboratory tube furnaces to 1800°C. Tube furnaces are available as single or multi-zone, horizontal/vertical, split & rotating models. A wide variety of tube diameters & tube heated lengths is available. Chamber furnaces are available in many sizes; models include high temperature furnaces, ashing/calcining furnaces, furnaces for the analysis of coal & coke and precious metals evaluation furnaces (cupellation/fire assay).

Industrial Furnaces

In addition to the range of electric laboratory furnaces, ovens and incubators, Carbolite also offers an extensive range of pilot plant and industrial furnaces and industrial ovens for various heat treatment applications. Product ranges include:

  • Mesh belt furnaces
  • Roller hearth furnaces
  • Rotary hearth furnaces
  • Top loading furnaces
  • Top hat furnaces
  • Blade strip hardening furnaces
  • Elevator hearth furnaces.

The range of industrial ovens includes both batch and continuous ovens. Examples of these are aluminum solution ovens, bogie hearth ovens, air recirculating chamber ovens and inert atmosphere ovens.

1700°C & 1800°C Laboratory High Temperature Furnaces (HTF & RHF)

HTF models

  • High temperature furnaces with maximum operating temperatures of 1700°C or 1800°C
  • 1700°C chamber capacities of 3 or 10 litres
  • 1800°C chamber capacities of 4 or 8 litres
  • Powerful MoSi2 elements located on both sides of the chamber ensure good thermal uniformity
  • Thick diameter MoSi2 elements can withstand the stress of everyday operation and provide good longevity
  • Low thermal mass insulation and good element design is used to ensure energy efficiency and rapid heating
  • Manually operated vertical counter-balanced door keeps hot door insulation away from operator
  • Positive break door safety switch isolates chamber from power supply, when the door is opened
  • Double skinned construction allows fanned air flow to cool the outer case, to conform to EN61010 safety standard
  • Eight segment programmer is fitted as standard, with options for other types
  • Adjustable over temperature protection is fitted as standard
  • Applications in general industry include sintering alumina, smelt trials and checking Al2O3 content in alumina
  • Applications in the ceramics industry include disintegration, testing and analysis of cement samples, refractory porosity tests, long term high temperature tests and firing & sintering of ceramic samples
  • Applications in the semi-conductor industry include annealing silicon, silicon carbide & nitride samples and solid state synthesis
